My niece's father thinks so too. He is an undergraduate who graduated from a famous school. What do you think? The answer to this question is 8. But I didn't expect my niece's answer to be deducted by the teacher, saying that all the answers to 8 were wrong.
Father thought the answer was incredible, so he contacted the teacher. The explanation given by the teacher is: You left me behind, and the correct answer is nine. Many netizens think that the teacher's explanation is simply "arguing irrationally". Am I a monkey?
In fact, when I saw this question, the answer in my mind was "8", but after hearing the teacher's explanation, I "suddenly realized" because we always put ourselves aside when calculating the problem.
According to the normal calculation logic, in the process of reading the topic, it is meaningful to increase the sense of substitution and regard yourself as the "I" of the article, that is, to count the protagonist in the topic in the calculation process.
However, many netizens will also question: Even if I count myself, I am still alone. The question is how many monkeys are there, so the answer is not eight.
The issue itself is very controversial. "The public says it's right, and the woman says it's right." . If you don't follow the correct answer completely, according to normal logic, "8" is actually right. After all, I am not a monkey.
It seems that the calculation problems of primary school students test students' thinking ability, but the calculation ability of students is still relatively good. If you want to learn math well and get excellent grades in the future, then strong computing ability is one of the necessary conditions for learning math well.
How to improve students' computing ability, strengthen oral arithmetic training and lay a good foundation for computing? Oral calculation is the basis of calculation. Only when students are proficient in oral calculation can they not be stumped in calculation, thus forming good calculation ability. Therefore, students can use morning self-study and other spare time to make some simple oral arithmetic cards.
Parents should also insist that students do oral math problems every day and gradually increase the difficulty on the basis of what they have learned, which is far more practical than signing up for some interest classes.
Students who pay attention to the cultivation of calculation habits often make the least mistakes when doing problems. Although some students don't study very well, they never lose points when calculating problems. This is because they have developed good calculation habits.
First of all, students must read the questions accurately before doing them, and make clear the relationship between the calculation order of the questions and the numbers. To form the habit of careful inspection, learn to check every calculation problem to see if there are any calculation errors or missing steps, and reduce the calculation error rate.
Paying attention to mathematical explanation and strong calculation ability are the basis of learning mathematics well. In fact, the calculation is very simple. As long as you master the calculation method, many simple calculation problems are basically needless to say. Every student can do calculation problems, but why is there always a big difference in calculation ability?
Teaching students to calculate should not be limited to "knowing how to calculate", but let them understand why they should calculate like this. Finding out the reasons is helpful to improve students' computing ability.
